anhydride with an alcohol, we're going to make an ester. So what's going to happen next is we're going to bring in this anhydride. And since it's a symmetrical anhydride, we can just say a portion of it will take the place of the hydrogen of the hydroxyl of this salicylic acid....
In an acidic medium, aniline forms a mixture of ortho and para-nitroaniline and also a significant amount of meta-nitroaniline. Acylation with acetic anhydride followed by nitration yields para-nitroaniline. c. Sulphonation With concentrated sulphuric acid, aniline forms anilinium hydrogen sulphate, whi...

Acetate (or cellulose acetate), produced by treating cotton with acetic acid and acetic anhydride, is also used in production of clothing. Hemicellulose is similar in structure to cellulose, but chains of hemicellulose are shorter and less stable. Soluble hemicellulose chains attract water and form...
